Pacemaker

[HdoubleS]

Hi
I'm working on a project for my biomedical course in university and my topic is about Pacemakers.
I was wondering if any one can help me find a data file or actual output signal of a Pacemaker so I can perform some analysis on it for my project. I am trying to compare the signal that is produced by the Pacemaker to the signals that is produced by the heart.

Thank you
